I’ve had my car buffed/polished before and at first it looked great, but after a few washes it deteriorated quickly, what happened?
A couple things… the most common reason that freshly detailed cars lose their shine so quickly is the soap and mitt that was used to wash it. You MUST use designated car wash soap or you risk striping the wax that was just applied. Your dish soap works great for dishes but it is too strong for a vehicle because it removes all the wax, leaving you with an unprotected and dull car. Secondly, if you use one of those common nylon wash mitts and your car is a dark color you will leave ‘spiderweb’ lines across the paint. These are small scratches that catch the sunlight just right and look horrible! To delay the onset of these imminent spider webs on dark cars use a cotton wash mitt instead. They are white and are available at most auto parts stores. These white cotton mitts won’t last as long as nylon or lamb’s wool but you’ll notice the difference in results.
